If you’re not familiar, Everdrives are flashcarts which store games via an SD card, and there are currently several on the market for cartridge-based systems, including the SNES. Thought I’d utilize the built-in LEDs, which happen to be the same colors as a traffic light, for this fun Mario Kart-inspired design.
Everdrives are a bit pricey but they can do some pretty cool stuff besides playing ROMs on original hardware, such as the ability to add CD-quality music to games. I would love to play Zelda: A Link to the Past with an orchestral score, or TMNT IV with arcade-quality music and sound effects.
